Kamerat is unique in at least two ways. It is among only a handful of film festivals in the world that specifically celebrate working-class film, and even fewer can boast of screening films in an abandoned mine shaft, forty metres below ground. This year it is happening for the third time and it features 22 films.

The festival was inspired by the 1934 workers' strike in Hrastnik, an old mining town where workers from all industries jointly demanded and achieved better working conditions.

It therefore takes place on the anniversary of the strike, with the local community celebrating solidarity, comradery and the importance of joining forces to achieve common goals.

This year's spotlight will be on Serbia, which has been chosen because of its long history of films about the working class, and the opening film on 29 June will be the Requiem for Mrs. J. by Bojan Vuletić.

Vuletić will be at the festival in person along with two other Serbian directors, Marko Cvejič and Marija Đoković.

Some of the film highlights include the documentary The Cacophony of Donbas (Kakofoniya Donbasu), the French film Full Time (À plein temps), and the Slovenian documentary Hungry, Barefoot and Famous (Lačni, Bosi in Slavni), which chronicles the unlikely success of a local choir in the 1930s.

The full programme, in Slovenian, is available here.
